Abstract: The dynamic balance measurement system of the precision
centrifuge is composed of four capacitance displacement measuring
instruments mounted on the upper and lower measuring planes, a
force-measuring sensor on the base and angle-measuring gratings. When in
quasi-static state and the balance velocity state the first harmonic
error is measured by five sensors respectively, the normal force upon the
pedestal is measured by the force-measuring sensor, the vibration vector
can be calculated by the output of four capacitance displacement
instruments. Comparing the output of four capacitance displacement
instrument to that of the force-measuring sensor, then the malfunction
judgement can be given. Applying the redundancy technology and
multisensor information fusion technology, the synchronized automated
data acquisition, processing and malfunction warning is realized by
computer.
